Definitions
- the invention relates to a compressor in a multi-stage axial design with a high fluid mechanical Efficiency, according to the preamble of the claim 1.
- the inlet side can on a so-called bearing star, i.e. to several, from the compressor housing struts leading radially to the center of the rotor and bearing the front shaft bearing, to be dispensed with.
- the blading is designed so that no static Inlet grille upstream of the first blade ring is required.
- the object of the invention is a compressor concept to propose with flying rotor bearings, with high operational reliability enables a reduction in the rotor weight.
- the invention proposes that at least one of the blade carriers in MMC construction (metal Matrix Composites) in order to counter the weight with the same strength reduce pure metal designs. This has a particularly strong effect there from where, for reasons of space, only annular blade carriers with a small radial cross-sectional height possible are.
- the rotary bearing supporting the rotor-bearing shaft end to be provided with a predetermined breaking point which, if a defined one is exceeded Radial load releases the rotor radially limited, so that by brushing against the rotor on the stator, combined with strong friction, wear and deformation, the even smaller rotational energy and unbalance due to weight reduction can be quickly reduced to "zero" if necessary. Overloading the compressor or Engine suspension is safely avoided in this way. The ultimately necessary The shutdown / shutdown of the compressor or engine is in contrast tolerable.
- Preferred embodiments of the compressor are in accordance with Main claim marked.
- the stator 2 of the three-stage compressor 1 according to FIG. 1 has an outer one, at least largely rotationally symmetrical housing 3 and three vane rings 4,5 and 6 on.
- the rotor 7 accordingly has three rotor blade rings 8, 9 and 10 on ring-shaped or disk-shaped blade carriers 11, 12 and 13.
- the rotor blade ring 8 forms the most upstream vane grille, the flow direction in compressor 1 accordingly runs from left to right.
- the rotor 7 with components 8 to 10 and 11 to 13 is overhung, i.e. with an over a pivot bearing 18 projecting shaft end 17 is connected.
- the shaft end 17 and the blade carrier 12 an integral unit, these could but also screwed together.
- the pivot bearing 18 is a radial bearing / floating bearing executed, here specifically as a cylindrical roller bearing. Usually with the fixed bearing cooperating further downstream / to the right is not shown since it is not part of the invention.
- the pivot bearing 18 is on the stator side with a frustoconical shape that widens in the downstream direction Carrier 30 connected, which in turn is firmly connected to the rearmost guide vane ring 6 is. This results in a relatively rigid connection of the pivot bearing 18 to the housing 3 of the compressor 1.
- the pivot bearing 18 takes due to its arrangement close to or in the center of gravity of the rotor 7 practically all of it radial loads attacking the latter.
- connection of the blades of the rotor blade rings 8 to 10 with their blade carriers 11 to 13 can be conventional positive or integral, the The tendency is towards integral blisk and bling designs, as shown in FIG. 1.
- the foremost blade carrier 11 forms one with its rotor blade ring 8 metallic blisk (bladed disk) without fiber reinforcement.
- the radial extension of the blade carrier cross section can still be relatively large at this point, i.e. strength technically unproblematic, an MMC construction would not be decisive here Offer advantages.
- the bird strike or FOD problem Form Object Damage
- the blade carrier 12 which has a bling (bladed Ring) in MMC construction. Due to the arrangement radially outside the Pivot bearing 18, the space constrains the radial cross-sectional height of the Blade carrier 12 serious, so that here an MMC construction significant savings in terms of material and weight.
- the most mechanically stressed fiber-reinforced area 14 is shown cross-hatched, the at least an, "endless” reinforcing fiber in a wound arrangement cohesively in the Matrix metal should be integrated.
- the blade carrier contour is dash-dotted for comparison indicated, which would be required without fiber reinforcement.
- the connection of the separate ring 20 is shown again enlarged in Figure 2.
- the pressure transmitting seat 25 is designed as a defined press fit, which alone is enough by calculation to axially and the ring 20 to be fixed tangentially to the blade carrier 13.
- the contact area on the ring 20 can be crowned in the sense of a favorable stress distribution (Hertzian pressure) be executed, the contact surface on the blade carrier 13 is cylindrical.
- As an additional Securing is complemented by a form-fitting fixation.
- This is the ring 20 with projections 21 distributed over its circumference, which in corresponding Engage recesses of the blade carrier 13.
- the extensions 21 have axial open grooves 22, the blade carrier 13 radially inward open grooves 23, in the Securing elements 24 in the form of rivets, pins, wires etc.
- the rotor blade ring 8 of the first stage has a so-called Casing treatment, i.e. combined with recirculation channels 32, which is suitable is to improve compressor stability. Such a measure can also be applied to others Compressor stages make sense.
- Figures 3 to 5 illustrate the aspect of overload protection by a predetermined breaking point 19 in the area of the pivot bearing 18.
- ball guides 26 used to deflect radial loads Fr into axial forces Fa under reinforcement. If defined axial forces are exceeded, axial tension screws 28 and release the pivot bearing 18 in the sense of limited radial mobility.
- the guide surfaces of the ball guides 26 are simple in the example shown to be assembled conical and cylindrical surfaces. The strengthening results from the cone angle. Of course, other geometries, e.g. with spherical areas.
- Figure 4 shows the triggered state Load exceeded with broken lag screws 28. It can be seen that the radial Relative displacement (here vertical) also a small axial relative displacement (horizontal here), due to the exit of the balls 27 from the conical surface.
- FIG. 5 shows an alternative design principle for a predetermined breaking point 19.
- Das Rotary bearing 18 is axially on both sides with shear rings in the area of its static outer ring 29 provided which positively in the outer ring of the pivot bearing 18 and engage in the carrier 30 or in elements connected to the latter. If exceeded a defined radial load Fr the shear rings 29 break suddenly without relevant plastic deformation.
- Metallic materials come for the shear rings 29 Materials, ceramic materials or even plastics into consideration, each without or with embedded additives such as particles, fibers etc.. Essential there is a fracture load that can be calculated and reproduced as precisely as possible.
- the triggered state with broken shear ring 29 and radial offset V is on the right the axial center of the rotary bearing 18 is shown.
- the pivot bearing 18 is sealed to the shaft with a brush seal 31, which behaves relatively tolerant of radial shaft deflections.
